On one MikroTik router, I want to divide my users to two groups and assign each group to a separate network (two networks).
How do I do that?
Any Suggestion ?
Thank you.
Via one ethernet interface
with vlan 2 and 3
networks 192.168.0.0/24 and 192.168.1.0/24
Via 2 interfaces
same networks, but without vlans
